| The purpose of establishing the physical examination and evaluation mechanism of urban resilience is to effectively monitor,analyze and evaluate the status of urban development,find out the shortcomings and deficiencies in urban development,avoid and prevent "urban diseases",and promote the construction of a healthy city with high-quality development of human settlements and modern governance capacity.Therefore,on the basis of clarifying the connotation and significance of urban physical examination and resilient City,this paper focuses on the eight dimensions of safety resilience,infrastructure resilience,traffic resilience,life resilience,social resilience,vitality resilience,ecological resilience and cultural resilience,aiming at promoting the revitalization of Northeast China,improving urban living environment and promoting the high-quality development of cities in Northeast China,and selects four major cities in three provinces of Northeast China as the research area,The urban resilience physical examination evaluation model and Arc GIS spatial analysis tool are used to evaluate the urban resilience physical examination of four major cities in three provinces in Northeast China in 2015,2018 and 2020.The geographical detector model and grey correlation model are used to explore the causes of spatial differentiation of regional overall and urban resilience development.Finally,the optimization strategy of urban resilience development is put forward.The results are as follows:(1)Evolution law of resilience in three provinces and four major citiesFrom the perspective of the region as a whole,the physical examination evaluation indexes of ecological resilience,infrastructure resilience and vitality resilience were high in 2015 and 2018.The four major cities have a good performance in the protection of ecological environment quality,the improvement of community service level and the improvement of urban innovation ability,while the urban social resilience and cultural resilience still need to be strengthened;In 2020,in addition to cultural resilience and vitality resilience,the resilience physical examination indexes of the four major cities decreased in varying degrees.The social resilience,traffic resilience and life resilience are weak on the whole.The commuting rate,city appearance and housing tolerance still need to be strengthened.From the perspective of cities,the overall urban resilience of Harbin and Changchun is in the trend of first rising and then falling,the urban resilience of Shenyang is in the trend of continuous decline,and the urban resilience of Dalian is in the trend of continuous rise.The resilience level of Dalian and Shenyang is significantly higher than that of Harbin and Changchun.The four major cities are generally good in ecological resilience and infrastructure resilience,but the social resilience index values are low.It is still necessary to improve the city’s social inclusion and housing inclusion.(2)Analysis on Influencing Factors of resilience of four major citiesFrom the perspective of the region as a whole,from 2015 to 2020,the impact of urban characteristics,housing inclusion,accident risk and social security on the resilience development of the four major cities in the three northeastern provinces has always been in the forefront.The characteristics of urban culture,talent attraction,urban safety and social security system play a vital role in the development of urban resilience.From the perspective of cities,public safety and convenient travel are the most critical factors affecting the urban resilience of Harbin,and resource utilization and urban comprehensive management ability are the secondary factors;Urban public safety and comprehensive management capacity are the main factors affecting Changchun’s urban resilience,while housing inclusion,population vitality and commuting efficiency are the secondary factors;The main factors affecting Shenyang’s urban resilience are population vitality and city appearance,and housing inclusion is the secondary factor;Housing inclusion and travel convenience are the main influencing factors of urban resilience in Dalian,while social security and group inclusion play a secondary role.(3)Optimal regulation strategy for resilience development of four major citiesUrban resilience is a dynamic development and change.Starting from the eight levels of safety resilience,infrastructure resilience,transportation resilience,life resilience,social resilience,vitality resilience,ecological resilience and cultural resilience,this paper puts forward overall regional optimization strategies and suggestions,and puts forward optimization strategies for each city respectively. |
